Trichoscopy as a Diagnostic Method in Non-Scarring Alopecia

The most common type of alopecia is androgenetic alopecia. It is estimated to affect about 80% of Caucasian men and about 42% of women. It is a serious problem that significantly reduces patients' quality of life. The second most common type is telogen alopecia. Also included in the study is alopecia areata, which affects up to 2% of the general population. Trichoscopy is a quick and precise diagnostic method for these types of alopecia. During a trichoscopic examination, we can visualize characteristic structures such as the perifollicular epidermis, hair follicle openings, and hair shafts. Using trichoscopy, it is possible to quickly determine the severity of hair loss and diagnose specific types of alopecia. Additionally, trichoscopy thoroughly allows for monitoring the response to treatment for various types of hair loss. The trichoscopic characteristics of different types of alopecia make it possible to identify the type of alopecia and choose the appropriate therapy. At the same time, other diagnostic methods take more time and are not as accurate in determining the problem. The aim of this work: This study aims to determine the usefulness and role of trichoscopy in the diagnosis and monitoring of non-scarring alopecia. Also, to explain the benefits and limitations of this diagnostic method and compare it to other methods. As a result, clinicians need to use this method as one of the first to diagnose non-scarring alopecia to begin appropriate treatment for a patient struggling with this problem as soon as possible. Methods: The research method was a thorough, critical analysis of scientific articles in the Google Schoolar and Pubmed databases. Content from 2012-2024 was reviewed however, most of the studies cited were published in 2018 or later. We focused on the characteristics of non-scarring alopecia, its trichoscopy features, and diagnostic methods. Conclusions: Trichoscopy is a simple, non-invasive method that may help diagnose various diseases with non-scaring alopecia. This method is painless, precise, and faster than others to diagnose and monitor non-scarring alopecia.
